Feeling very negative inside

I don't know why I let these things bring me down but when it's family causing the grief it's bound to happen. I'm being shut out and it's difficult to handle. I feel adopted which I am just feeling excluded from any decision making with my father I give up. Not that I think I should be making any but I can't even support any that have been made. I've been cut off from the family by them. I don't know. Oh well what can you do so I feel that I'm better of not getting involved. I can't change it so there fore I should let it go. There is a shower for my nephew's wife for the baby and I really don't feel like going now. I think I'll be sick that day. It's the best way out. It's just painful being around them emotionally right now for me. I don't know what to do you get tired of being the better person and going. I just don't have it in me. It's time to move on and let them get on with it. I know it sounds childish but how many times can you be let down in your life.
I'm working today and the rest of the week which is probably good for me to be busy. Work yesterday was busy for me but I was able to keep up. I said that I was going to do some photo books for two of the girls that are going to retire. So that should keep me busy. Well I guess I should stop now and get ready for work I'll write later or tomorrow.
